TM172 "random" Warnings

[otrotabi]

I get these warnings while compiling:

warning A4103: SYSFTP_COD_FILEFILTER => Data block not found
warning A4103: SYSIP_ADDRESS => Data block not found
warning A4103: SYSDEFGTWY_ADDRESS => Data block not found
warning A4103: SYSPRIDNS_ADDRESS => Data block not found
warning A4103: SYSSECDNS_ADDRESS => Data block not found
warning A4103: SYSMODBUS_MSG_RECEIVED_USB => Data block not found
warning A4103: SYSMODBUS_MSG_RECEIVED_RS485_1 => Data block not found
warning A4103: SYSMODBUS_MSG_RECEIVED_RS485_2 => Data block not found
warning A4103: SYSMODBUS_MSG_RECEIVED_RS485_PLUGIN => Data block not found

However, these mesages seem to pop-up almost randomly.

I am not implementing these functions, neither ftp or modbus access in this project.

These are datablocks of TM172, maybe you are compiling connected to a different target (check your current connection settings), if this is the case the SW will upload the target image of what is connected.

A "refresh current target" (from menu Project), before compiling should solve the warning issue.

Checking your answer, it looks right. I got the warnings, refresehed the target and compiled again and the warnings disappeared.

If you can further help me, I would like to have any idea of the different targets available. For example, this project is for a TM172PDG28R. If I select Project/Select target the choice here is quite obvious.

However when I connect to the actual PLC, I get a warning, telling me that I am trying to connect to a different release (I recall maybe 596.10 instead of 596.12 but I am at home now). 

In any case programming works fine at the real PLC so I have never bothered too much about these warnings. Is it advisable to go to Commissioning/Bios Downloads and upgrade the firmware ? Does this solve this other issue ?

Warning comes when the project target is different from the plc fw version.

You should have always plc version equal or higher than the project version, e.g. m172 596.12 project 596.10.

This situation can causr a warning but it is not a problem, to avoid it you have to update the project target (I prefer to update project only when it is rrally necessary).

The opposite situation can cause a problem in case the project uses some datablocks or target blocks not defined in the old bios version.

It is better to upgrade the bios to the latest version available.
